摘要
论述了80万t/a合成氨装置工艺烟气管道技改时,从管道壁厚校核、ASME判断式分析、经验判断、CAESAR Ⅱ软件校核等四个方面进行管道柔性设计的分析过程。最终采用设置两个万向铰链式膨胀节的方式,吸收管系端点的水平推力,保证管系与原有设备和管道能稳定运行。
It is discussed that the flexible design and analysis process of flue gas pipeline has been done through four aspects: pipe wall thickness check, ASME judgment simple analysis, experience judgment and CAESAR Ⅱ software check. Finally, two universal hinged expansion joints are set up to absorb the horizontal stress at the end of the pipe system, so that the pipe system can run stably with the original equipment and pipeline.
